Abstract

In forming yarn and yarn-like structures separate multifilament strands (1, 2, 3) of thermoplastics material are treated so that at least one (2, 3) has a shrinkage ratio higher than normal at an elevated temperature. The strands are intermingled in a gas stream with formation of loops (21) on the strands, the yarn so produced is subjected to a twisting force and is then heated to cause the filaments to shrink differentially while being held to a predetermined length, then cooled while being held until shrinkage ceases. <??>The yarn produced is highly flexible, of uniform cross section and shows no tendency for the strands to separate. It has also a high degree of softness and tenacity.
